On some models, spacetime has no beginning. This is usually either because it extends infinitely into the past or because time deconstructed in some sense. Is one of these models which lack a beginning true?
Physical reality (all spacetime) began to exist.
This page analyzes six evidences,…
This is relevant because if physical reality began to exist, then no beginningless model is true.
The Aguirre-Gratton reversed arrow-of-time model is true. This is relevant because the model lacks a beginning.
The Carroll-Chen reversed arrow-of-time model is true. [See full article.] This is relevant because the model lacks a beginning.
